Answer:
5/b
Step-by-step explanation:
you would want to add your 1+4 together on top of your b which is your common denominator in this case and you should end up with 5/b
Answer:
36/6, 72/12, and 6/1
Step-by-step explanation:
18/3=6, so we just need to find the fractions that simplify into 6 (we reduce fractions by dividing the numerator and denominator by the greatest common factor, in this case the number must be whole, so we are just going to divide the numerator by the denominator). 90/16=5.625, it does not equal 6, so it is not proportional to 18/3, this is also true for 36/12=3. 36/6=6 so it is proportional, so is 72/12=6 and, obviously 6/1=6 so it, too, is proportional to 18/3.
The equation to find volume is V=

r²h and you know all of your numbers other than h so you plug all that in. 100=3.14×2²×h → 100=3.14×4×h → 100=12.56×h → Divide 12.56 from both sides 100÷12.56=12.56×h÷12.56 → 7.96cm=h.
I hope that helps!
